The UN Security Council on Tuesday unanimously adopted a resolution to slap sanctions on South Sudan's warring factions, ratcheting up pressure as a deadline loomed to reach a peace deal. Drafted by the United States, the resolution sets up a sanctions committee which would submit to the council the names of those responsible for blocking peace efforts, and who should be punished with a global travel ban and assets freeze. Regional mediators have given South Sudan's President Salva Kiir and rebel chief Riek Machar until Thursday to reach a final deal to end 14 months of war that have killed tens of thousands of people.
